gcc-10: options order important?

["Piotr A. Dybczyński" <piotr@dybczynski.pl>]

Hi,

in contrary to previous versions, now in Debian 11 with gcc-10:

gcc aa.c -lm -o aa           works, but

gcc -lm aa.c -o aa           does not work, saying: 

/usr/bin/ld: /tmp/ccWyhudO.o: in function `main':
aa.c:(.text+0x1f): undefined reference to `sqrt'
collect2: error: ld returned 1 exit status

My aa.c content:

-------------------------------------------
#include<stdio.h>
#include<math.h>

int main(void)
{
  double x=4;

  printf("sqrt(4)=%f\n",sqrt(x));

  return 0;
}
-------------------------------------------

It seems that an option -lm cannot be placed in an arbitrary place which I used to
do. Is this intentional ?
